BAGKWATER-INTERCEPTING TILE-DRAIN SUMP.

Application filed April 14, 1928. Serial No. 269,986.

This invention relates to bacl: water intercepting tile drain sumps andthe object of the invention is to provide a means for preventing sewagefrom backing up from the main house sewer into the field tile drainsaround the basement wall and at the same time will provide drainage aslong as the water in the sump remains below the inlet valve.

A further object of the invention is to provide an outlet member adaptedto be connected to an outlet pipe and adapted to be turned on itsvertical axis in relation to the sewer trap body for connection to theoutlet pipe, the outlet member being adapted to be calked in any setposition in the trap body.

These objects and the several novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawings in which Fig. 1 is a plan view of a back waterintercepting tile drain sump embodying my invention.

Fig. 2 is a section taken on line 2-2 of Fig. -1.

The device comprises a main body member 1 having an inlet 2 to which atile drain may be connected. The inlet 2 opens into a chamber 16 formedin one side of the body member 1. As shown in Fig. 2 a valve seat memher3 is threaded into the inlet 2 from the inside of the drain sump and isprovided with a lug 4 extending from the top thereof. This lug 4provides a pivot for the swinging arm 5 to which the valve 6 is securedand the member 3 is faced off at the end to provide a seat for the valve6 which normally rests thereon by gravity. This valve and member 3 arepositioned in the chamber 16 at one side of and out of the main chamberin the body member. A clean-out plug 7 is threaded into the upper end ofthe body member 1 and allows access to the interior of the body memberfor cleaning and as the valve 6 and valve member 3 do not extend intothe main chamber they do not interfere with cleaning. The member 1 isprovided with an offset portion 8 at the side opposite the inlet 2providing an annular seat 9 on which the outlet member 10 is adapted tobe positioned within the annular flange thereabout. The outlet member 10is provided with a vertical opening therethrough and with an outletopening. 11 opening from the side thereof which is adapted forconnection with an outlet )ipe. The outlet member 10 may be turned toany angle on the 9 on its vertical axis to position the outlet 11 at anydesired angle to acconi modate the drain sump for connection with theoutlet drain pipe. When the member 10 has been correctly positioned inrelation to the body member 1 it is calked in position in the offsetportion 8 by means of the callting 12. A clean-out member 13 ispositioned in the flange 14 on the upper end of the member 10 and issecured in this flange by calking as shown and a clean-out plug 15 iscarried in the upper end of the member 13 and allows access to theinterior of the member 10 for cleaning.

lVhen the tile drain is connected to the inlet 2 and the outlet drainpipe is connected to the outlet 11 the water will stand in the drain atabout the level shown in Fig. 2 below the inlet valve 6. Any watercoming in through the field tile inlet will swingthe valve 6 off fromits seat and flow into the in terior of the body member 1. Should thedrain water back up in the outlet and fill the drain sump the pressureof the water will more firmly close the valve 6 and prevent the waterfrom backing up into the field tile drain.

From the foregoing description it becomes evident that the device isvery simple and efficient in operation, will not easily get out oforder, may be adjusted to accommodate the drain sump for use with inletand outlet pipes at different angles and provides a device whichaccomplishes the objects described.

Having thus fully described my invention. its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. A back water intercepting tile drain sump comprisinga substantially cylindrical body member provided with an offset chamberhaving an inlet thereinto, a valve member threaded into the inlet fromthe inside of the body member and extending into the chamber, the valvemember being provided with a valve seat on the end thereof, a valvepivotally mounted on the valve member and normally engaging the valveseat by gravity, the valve and valve member being mounted in the saidchamber at one side of the said body member, the body member beingprovided with an outlet opening and an outlet member supported in theoutlet opening and having an outlet in the side thereof.

2. A back water intercepting tile drain sump comprising a body memberhaving an inlet in the side thereof, a valve normally closing the inletagainst back pressure by gravity but allowing flow from the inlet intothe body member, a clean-out plug in the top of the body member, thebody member having an offset outlet near the bottom provided with anannular flange, an outlet member positioned in the annular flange andadapted to be turned on its vertical axis, the outlet member having anoutlet in the side thereof and being adapted to be calked in anyposition in the said flange, a clean-out member secured to the top ofthe outlet member, and a clean-out plug threaded into the clean-outmember.

3. A back Water intercepting tile drain sump comprising a body memberhaving an inlet in one side thereof, a valve member threaded into theinlet from the inside of the body member and provided with a valve seaton the end thereof, a valve pivotally mounted in relation to the seatand normally closing the inlet to back water pressure by gravity,

the body member being provided with an outlet opening, an outlet membersupported in the outlet opening and having an outlet opening in the sidethereof, the said outlet member being turnable on its vertical axis inrelation to the said body member and being adapted to be secured to thebody memher in any position by calking.

4. A back water intercepting tile drain sump comprising a body memberhaving an inlet in one side thereof, a swinging valve closing the inletagainst back pressure, the body member having an outlet provided with anannular flange, an outlet member seating in the said flange and beingadapted to be turned on its vertical axis in relation to the bodymember, the said outlet memberbeing secured in any position to the saidflange by calking and having an outlet on the side thereof, and aclean-out member and plug secured in the upper end of the outlet member.

In testimony whereof I sign this specification.

EDWARD V. N. BOOSEY.
